In the webview, you can't go back to the app's previous screen.

I compiled this app, it works, but there's a problem. After opening the webview, the return key can't return to the last page of the app, directly let the app run in the background, wake up the app again, black screen. Is there any solution? My phone is huawei mate9.

I tried it using Kivy Launcher and it works as described. You can even navigate inside the webview, and press back untill you get again the Kivy controls instead the webview.

Seems it's a bug produced in your particular compilation, a problem regarding your Android version or other, but not a problem with the code itself.
